Gpt Auxiliary Connector - Simrad ES70 - INSTALLATION REV A Installation Manual

GPT Auxiliary connector

The ES70 General Purpose Transceiver (GPT) board contains a 25-pin female Delta
connector handling various external interface signals.

Interfaces on the Auxiliary plug
• Analogue heave sensor (pins 3 and 16)
One differential input is connected to the sensor output terminal, the other input
is grounded at the sensor in order to prevent ground potential offsets between the
sensor and the transceiver from being adding to the sensed signal. The differential
input range is ±10 V.
Note
This input is not supported by the ES70 Fish finding echo sounder.
• Temperature sensor (pins 4 and 17)
Some transducers contain a built-in temperature sensitive resistor, normally 10 kohm
at 25°C. This resistor is used to measure the water temperature.
Note
This input is not supported by the ES70 Fish finding echo sounder.
